"Two robbers have paid a visit to a house in south-eastern Australia, hours after a teenager posted a photo on Facebook of a large sum of cash. The masked men, armed with a knife and a club, struck the home of the 17-year-old girl's mother in the country town of Bundanoon on Thursday, police say. Her mother told the men her daughter no longer lived there. It is not clear how the robbers found the family address. The Facebook image was at the grandmother's Sydney house. The men searched the house and took a small amount of cash and a small number of personal objects before leaving. No-one was injured." Should I be laughing or crying?
